' mourn-FLOW GOVERNOR.

Applicationled April 5, 1924. Serial No. 704325.

My invention relates to means for Govern-' ing the flow of liquids from pipe lines or reservoirs, and more particularlyto means for governing such. flow when there is a multiple source of supply.

One of the objects-of my invention is'to provide a governor whereby the flow may be limited to one or more of the sources of multiple supply. Another object is to selectively combine the several units of such supplies. A third object is to regulate the proportions in which such units may be combined.l Other objects will become apparent from the detailed description which follows.

Figure 1 is a view of one of the forms of my invention in cross section throuOh a vertical plane. Figure 2 is a top view 0I the same form, partly in cross section through the line 2 2 of Figure 1. Figure 3 is a detail of the same form in cross section along the line 3 3 of Figure 1. Figures 4 and 5 are cross sections of another form of my invention, taken vertically and horizontally, respectively, Figure 5 being a cross section along the line 5 5 of Figure 4. Figure 6 is a front view ofstill another form of my invention, partly in cross section. Figures 7 and 8 are details of the form shown in Figure 6, being cross sections along the lines 7 7 and 8 8 of Figure 6, respectively. Figure 9 is a front view of another modification of my invention, partly in cross section.

c, schematically illustrate the operation of mdevice, as will be duly explained below. eferring more particularly to Figures 1 and 2, 1' and 1" are tWol chambers of a vessel separated from one another by the valve seat 2 formed partly by the walls of said chambers; into said valve seat 2 fits loosely the valve 3 which may be turned by meansl of the handle 4. Into the Valve seat 2 enter the supply pipes 5' and 5" conveying different liquids to the chambers 1' and 1" respectively through the passage wayS'G and 6" in the 'valve 3 and the outlets 7 and 7"- of said passage ways, and the ports of entry 8' and 8", to said chambers, when the outlets 7' and 7" register with the ports of entry 8' and 8", as they de in the drawing. The chambers 1 .and 1" have exit ports 9 and 9" which register with the slots 10, 10, in the lower, hollow end of the valve 3 when the valve 3 is turned to a Figure 10, with its steps a, I), c, d and e, and Figure 11, with its steps a, b and proper angle. When the slots 10, 10, register with the exit ports'9'. 9" the outmetrically opposedto one another, so that it is possible to turn the Valve either into a position where only one of said slots l() registers with one or the other of the exit ports 9', 9", or linto a position where both slots 10, 10 register with said two exit ports,

or, it' so desired, one or both slots 1() may only partially register with the exit ports.

On' top of each chamber 1' 1' are covers 11',

11", tightly fastened thereto by means of screws or bolts 12, and bearing the plungers 13', 13", of standard construction and adjustable to various heights by means of the threaded members 14', 14' The movement of a plunger 13 is possible so long as the cone 15 has not reached the correspond-A ing conical seat in the threaded member 14', as shown in Figure 1, on the left side. the right side, the plunger! 13" has reached the limit of its motlon, the cone 15" having reached its seat in the member 14". The entire governor, including the two chambers l', 1", and valve 3, may be attached to any suitable place by means of the brackets The on] diil'erence between t-he forms shown in igure 1 and in Figure 6 is in the arrangements of the slots in the hollow end of the valve 3. As shown in Figure 6, in conjunction with detail Figures 7 and 8, the two slots 10a and 10b areI at different heights, for purposes Whichv will be explained later. In the form ofmy'finv'ention shown in F igure 9, I use .only one chamber, l", with all the elements appertaining thereto as in the forms disclosed'in Figures l and 6, but the other chamber 1 is replaced'by the pipe 17 which takes place of the entry port 9'.

In Figures 4 and 5, I show another modification of my invention wherein both the chambers 1' and 1" are eliminated and the liquid is'supplied to the valve directly from several sources (four only shown in the drawings) by means of the pipes 18, 19, 20, 21. In this case, i. e., when the number ot' supply sources is greater than three, I prefer to use a sleeve 22 between the valve 3 and the valve seat2, a second handle, 23, being provided to turn the sleeve 22 independently of the valve 3. The sleeve 22 has a suitable number of portholes 24 which may register with the slot 25 in the valve 3, at which times the liquids entering through one or more of the pipes 18, 19, 20, 21, according to the position of the sleeve, will emerge through the open end 26 of the valve 3.

The tive schematic figures of Figure l0 show various positions of a valve with regard to the valve seat when there are three sources ot' supply, 1, 2 and 3 being three exit ports from reservoirs or pipes, and l, 5 and 6 being three slots inthe hollow open end of the valve. It will be seen that in the position, Figure 10, no liquid can pass through; in the position of Figure 10b, only liquid from source 1 may pass; in the position, Figure 10c, only liquids from sources 1 and 3 may pass; in the position, Figure 10d, liquids may pass from all three sources; and in the position, Figure 10e, only liquids from sources 2 and 3 may pass. It should be noted that intermediate positions of the valve will allow some or all of the liquids to be discharged only partially, by incompletely registeringI the slots and ports.

The three schematic figures of Figure 11 Vshow some of the positions of a valve with regard to the valve seat when the particular object in view is to not only shut off oneor the other of two sources of supply, but to be able to regulate the proportions in which the. two supplies may be combined in the discharged low. Figure 11a shows the position of such a valve when both supplies are shut off; in Figure 11b, only one of the two sources is allowed to furnish the discharge flow; and in Figure 11", one source is permitted to discharge in full, while the other discharges only a proportion of the full amount which it is capable of discharging. Other positions, not shown, would furnish all sorts of proportions between the two supplies that one may desire to obtain. Ot course, the ports and slots may be arranged in a great many other ways. The drawings here shown are merely for the purpose of illustration.

The method of operating my governor will 110W be briefly described. Considering first the form shown in Figures 1 and 2, ad'ust the two plungers 13', 13" to different heights by regulating the positions of the threaded members 14', 14". The handle 4 is turned to a position whereby the ports of entry 8', 8" register with the outlets 7', 7" of the passage ways 6', 6". The two chambers 1', 1" will fill up to dii'erent levels, according to the adjustment of the plungers, the inow of liquids being stopped when the cones 15', 15" reach their respective seats in the members 14', 14". Combe secured through the port ot' exit 9".

'lov

their contents through the open end of the valve 3. While the chambers are being emptied the morts of entry 8', 8" are out of regist er with 'the outlets 7', 7".

In operating the form shown in Figure (i. the chambers will not be completely emptied', each chamber being reduced of its contents only downto the corresponding level ot' the slot 1()a or'10?.

I may, of course, have more than two chambers in my governor. In the case ot three such chambers, I use an arrangement of exit ports and slots illustrated in Figures 101L to l0". Or, I may have only one chamber, as shown in Figure 9, the second supply coming directly through a pipe 17. This arrangement is well adapted, Jfor instance, to soda fountains. The supply of water or carbonated water would be obtained through the pipe or opening 17, while a supply of syrup or phosphate, regulated as explained in regard to the operation of the chambers in the other forms of my invention, would Of course, in this case, also, I may use slots at various heights, as in the case of Figure 6. Finally, I may dispense with chambers altogether, as in the case illustrated in Figures 4 and 5. When I have only two or three sources of supply, the sleeve 22 is not necessary. I wonld, in this case, use an arrangement as shown for. the left side of Figure 9, and the schematic slot arrangement of Figures 10l1 to 1()e (for ,three sources), or the slot arrangement of Figures 11u to 11c (for two sources). But when I have more than three sources of supply, I prefer to use a sleeve 22, as illustrated in Figures 4, 5.
